Gravel Substrate stuff?
Stupid Stupid questions but-
what does gravel substrate actually do?
I have boiled ( 60 seconds a rock, VERY carefully) tumbled rocks, and i clean them (hot water and cloth) when i clean my tanks... But i read that i should have Substrate, so i bought some white gravel substrate... and it says rinse till the water runs clear to remove dust. So i did, and it still has dust in it when i put it in the tank, i have rinsed it VERY well probably 15 times, and it still has dusty (like ground up rocks) stuff. I suspect its just the rocks wearing each other down during shipment and stuff... How do i get rid of it? or does it not matter if it is there? I don't want to put it in till i know for sure
